Buried Alive (1990)

Produced for cable TV, this pedestrian thriller (also known as Till Death Do Us Part) purports to be a riff on Edgar Allen Poe's "The Premature Burial" but actually bears more of a resemblance to Diabolique. It stars Tim Matheson as a cheated-upon husband who can't stay down after his wife's (Jennifer Jason Leigh) unsuccessful attempt to poison him results in his being buried alive. The film's one real moment of horror comes in a claustrophobic sequence where Matheson desperately claws his way out of his coffin. The story then settles into a standard revenge motif, capped with an admittedly potent payoff that, though intriguing, is probably not as shocking as the filmmakers had intended.
